T 0 all/whom t mayco-ncern.' i

Be it known that I, FREDERICK 0. SNOW, Jr., a citizen of the United States, and a resident of I'Vinchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement in vinches, of which the following description, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts. l

This invention relates to l cable-winding mechanisms, and is more particularly concerned with winches.

The invention will be best understood by reference to the following description, when taken in -connection with the accompanying drawings of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is an elevation, partly in vertical section, showing a winch exemplifying my invention; and

Fig. 2 is a sectional view on line 2-2 of ig'. l. Referring to the drawings, and to the embodiment of the invention which is selected for exemplication, there is shown a winch having a winch head 10, Which may be, and is herein, vertically disposed, although it may be otherwise ,arranged to suit the requirements of the situation. The winch head is rotatably mounted on an appropriate support, herein a base 12 having an elongated boss Or post 14, formed as an integral part thereof, presenting bearing surfaces 16 and 18, the lower preferably larger in diameter than the upper. erein, the winch head is provided with webs 2O and 22 and hubs 24 and 26, preferably provided with bushings 28 and 30 mounted to turn upon and about the bearing surfaces 16 and 18, respectively. These bearings are provided with suitable lubricating means, herein a grease cup 32, feeding grease through a main duct 34 and branch ducts 36 and 38 'to grooves and 42, respectively, in the bearing surfaces 16 and 18. i

Preferably, the post 14 and base 12 are hollow, thereby presenting maximum strength and minimum weight, as well as affording excellent ventilation to keep the bearing properly cooled, the base and column, to these ends being provided with l an axial chamber 44. The winch head'is `suitably had in Serial N0. 466,444.

place On the post as by a ring-like washer 46, hereinsecured-to the postby one or more cap-screws 48. This washer may present a convenient mounting forthe grease cup 32, which in the present example is provided with a threaded stem 50, screwed into the washer.

That is above the web 20 in the present embodiment is entirely open and requires no coverplate, ythe elimination of the latter saving portion of thewinch head 10 whichv COMPANY, or EAST BOsTON,` MASSACHUSETTS, A'

weight.l Should any water entertheex posed upperportion of the spool, it willv drain off through one Ormore openings 52 provided in the circumferential wall of the spool above the web 20, and preferably below the top kof the hub 24.

. The spool is rotated by a suitable driving mechanism, herein comprising a worm 54 and worm-gear 56 (see Fig. 2), thelatter being secured to lthe winchhead as Vby providing the same with a flange 58 perforated to receive cap-screws 60 threaded into the web 22 of the winch head (see Fig. l). The flange 58 rests upon a shoulder 62 on the post or column 14, and sustains the weight v of the winch head The should be evident Without further description, it being understood that a'cable will be coiled about the spool in'a usual and well-known manner, and its free end will be held in the handsv of the operator, who takes in or pays out the slack as the winch head rotates. The Winch may be utilized for a wide variety n the present embodiment for use as a car puller. The base 12'may be suitably secured to any appropriate fixed or movable platform or other mounting.

Having thus described y of my invention, but without limiting myself thereto, what I claim and desire by Letters Patent to secure is:

1. In a winch, the combination of a onepiece base and column presenting inner and outer chambers one about the other, a winch head journaled about said inner chamber, and gearing Within said outer chamber for driving said winch head.

2. In a winch, the combination of a onepiece base and upright column presenting an inner chamber and an outer chamber separated by an intermediatewall which eX- tends inward and upward, a winch head and worm gear.

general operation of the machineA one embodiment said column and*l about journaled about said column, and gearing within said outer chamber for driving said winch head.

3. ln a winch head, the combination of a one-piece base and Column presenting inner and outer chambers, one about the other, and separated from each other by an intermediate wall which presents an external bearing' surface and which wall is provided with a lubricant conduit leading to said bearing, surface, a vwinch head journaled about said column and on said surface. a retainer secured to the upper end of said column and overlying a part of said winch head to limit upward movement of the latter, means supported by said retainer to feed lubricant to said conduit, and gearing within said outer Chamber' for driving; said winch head.

4. ln a winch, the combination of a winch head7 a base, a hollow post 'upstanding therefrom and presenting bearingr surfaces for said winch head, said post having a circumferential wall provided with a passage leading,` to said bearing surfaces 'for conducting lubricant thereto.

5. In a winch, the combination of a base-- a post su ported thereby, and a winch head supporter by said base and mounted to turn on a bearing on said post, said head being open at its top, and provided below said bearing with one or more passages Jfor the escape of water.

6. In a winch` the combination of a base, a post supported thereby, and a winch head supported by said base and mounted-to turn on said post, said head being open at its top, and having a laterally disposed annular wall provided with an outwardly extending passage' Jfor the escape of water -from a point intermediate the top and bottom of said head.

In testimony whereof, l have signed my name to this specilioat-lon.
